SAFETY WINDOW-CATCH.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed May 6. 1907. Serial No. 372.273.

To all whom it may concern:

Be it known that 1, LE ROY D. WAY, a citizen of the UnitedStates,residing at Rugby, in the county of Pierce and State of NorthDakota, and whose postofiice address is Rugby, North Dakota, haveinvented new and useful Improvements in Safety Window- Catches, of whichthe following is a specification.

My invention is a safety window catch, which may be appliedto and usedon any window where the sash slides up and down.

The object of my invention is to securely hold a window sash at anypoint placed, and to permit it to slide up and down when desired.

In the accompanying drawings, Figure 1, is a face view of my invention,the top plate removed. Fig. 2, is a rear view. Fig. 3, is a crosssectional view, on the line 3, 3, of Fig. 1, looking from the front end.thereof. Fig. 1, is a longitudinal sectional view, on the line 4, 4, ofFig. 1.

Similar letters refer to similar parts throughout the several views.

In describing my invention I read the drawings from left to right.

My invention is described as follows:

In the accompanying drawings, the letter a, represents eccentric wheelspivoted to the face of the bottom plate a near the front end thereof.The periphery of each wheel is grooved as shown at 6 and is covered by arubber band I); 0, represents rivets in which said eccentric wheelsturn; d, represents elbow levers, pivoted to the plate at their elbowsby means of pivots 6, their free ends extending rearwardly through aslot (L in the flange a of said bottom plate (1 The said eccentricwheels, each has extending from its periphery a short arm a, and pivotedto each of the said short arms are the front ends of links f; the rearends of these links are pivoted to the extreme forward ends of thefore-arms d of said elbow levers (Z. Secured to said links, near theirrear ends, is a coiled spring 9, in such position as to pull the saidrear ends of said links together, and thereby open the rear ends of saidelbow levers, and at the same time throw said short arms a, of saideccentric wheels a, forward, and thereby throw said Wheels against thesaid bottom plate 0).

window casing, and thus hold the sash firmly in the position placed.

When I wish to move the sash up or down, I press the free ends of theelbow levers together which has the effect, by means of the mechanismjust described, of withdrawing the said wheels from said sash. The saidplate a is provided at its center with a threaded elevation h, and bymeans of a screw 1, the top plate a is fastened to the The device issecured to the sash by means of screws, which pass through screw holes"L, in the top and bottom plates.

Although I have specifically described the combination, construction andarrangement of the several parts of my invention I do not confine myselfparticularly to such specific combination, construction and arrangement,as I claim the right to make such changes and modification therein asmay clearly fall within the scope of my invention, and which may beresorted to without departing from the spirit, or sacrificing any of mypatentable rights therein.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

A safety Window catch, consisting of a bottom plate a provided with aflange (1 having a slot (1 a central threaded elevation h, and screwholes i; eccentric wheels a, having their periphery grooved, pivoted tothe face of said plate near its front end; rubber bands I), covering theperipheries of said wheels; elbow levers d, pivoted to said plate nearits rear end; short arms a, extending from said wheels a; links f, theirfront ends pivoted to the free ends of said short arms, their rear endsto the extreme forward ends of the fore-arms of said elbow levers; a

, coiled spring secured to said links near their rear ends, in positionto hold said wheels against the window casing, and a top plate a securedto said bottom plate by means of a screw f, substantially as shown anddescribed and for the purposes set forth.
